Triticeae

Triticeae is a taxonomic tribe within the subfamily Pooideae of the family Poaceae. It includes some of the most important domesticated cereal crops, such as wheat, barley, and rye. The tribe is named after the genus Triticum, which includes the wheat species.

Taxonomy

The tribe Triticeae is classified within the subfamily Pooideae, which is itself part of the grass family Poaceae. The tribe is further divided into several genera, including Triticum, Hordeum (barley), and Secale (rye). Other notable genera in the tribe include Aegilops, Elymus, and Agropyron.

Economic Importance

Triticeae crops are of significant economic importance worldwide. They are staple foods in many cultures and are used in a variety of food products. Wheat is used to make bread, pasta, and pastries, while barley is used in the production of beer and whiskey, as well as in soups and stews. Rye is used to make bread and whiskey, and is also used as animal feed.

Cultivation and Harvesting

Triticeae crops are typically grown in temperate regions, although some species can tolerate more extreme conditions. They are annual plants, meaning they complete their life cycle in one year. The seeds are sown in the autumn and the plants grow throughout the winter, with the grain being harvested in the summer.

Genetic Research

Triticeae crops are also important in genetic research. The tribe includes several model organisms, such as Triticum aestivum (bread wheat), which has a fully sequenced genome. This research has led to advances in plant breeding and has improved our understanding of plant genetics.
